It pushes the boundaries of translation capabilities within 7 billion parameters\. We develop Seed\-X as an accessible, off\-the\-shelf tool to support the community in advancing translation research and applications: \***Exceptional translation capabilities**: Seed\-X exhibits state\-of\-the\-art translation capabilities, on par with or outperforming ultra\-large models like Gemini\-2\.5, Claude\-3\.5, and GPT\-4, as validated by human evaluations and automatic metrics\. \***Deployment and inference\-friendly**: With a compact 7B parameter count and mistral architecture, Seed\-X offers outstanding translation performance in a lightweight and efficient package, ideal for deployment and inference\. \***Broad domain coverage**: Seed\-X excels on a highly challenging translation test set spanning diverse domains, including the internet, science and technology, office dialogues, e\-commerce, biomedicine, finance, law, literature, and entertainment\. This repo contains the**Seed\-X\-PPO**model, with the following features: \* Type: Causal language models \* Training Stage: Pretraining & Post\-training \* Support: Multilingual translation among 28 languages LanguagesAbbr\.LanguagesAbbr\.LanguagesAbbr\.LanguagesAbbr\.ArabicarFrenchfrMalaymsRussianruCzechcsCroatianhrNorwegian BokmalnbSwedishsvDanishdaHungarianhuDutchnlThaithGermandeIndonesianidNorwegiannoTurkishtrEnglishenItalianitPolishplUkrainianukSpanishesJapanesejaPortugueseptVietnameseviFinnishfiKoreankoRomanianroChinesezh## Model Downloads Model NameDescriptionDownloadSeed\-X\-InstructInstruction\-tuned for alignment with user intent\.🤗[Model](https://huggingface.co/ByteDance-Seed/Seed-X-Instruct-7B)👉**Seed\-X\-PPO**RL trained to boost translation capabilities\.🤗[Model](https://huggingface.co/ByteDance-Seed/Seed-X-PPO-7B)Seed\-X\-PPO\-GPTQ\-Int8Quantization: GPTQ 8\-bit\.🤗[Model](https://huggingface.co/ByteDance-Seed/Seed-X-PPO-7B-GPTQ-Int8)Seed\-X\-PPO\-AWQ\-Int4Quantization: AWQ 4\-bit\.🤗[Model](https://huggingface.co/ByteDance-Seed/Seed-X-PPO-7B-AWQ-Int4)Seed\-X\-RMReward model to evaluate the quality of translation\.🤗[Model](https://huggingface.co/ByteDance-Seed/Seed-X-RM-7B)## Evaluation We evaluated Seed\-X on a diverse set of translation benchmarks, including FLORES\-200, WMT\-25, and a publicly released[challenge set](https://github.com/ByteDance-Seed/Seed-X-7B/tree/main/challenge_set)accompanied by human evaluations\.For detailed benchmark results and analysis, please refer to our[Technical Report](https://arxiv.org/pdf/2507.13618)\. ## License This project is licensed under OpenMDW\.
